Gary I was out yesterday with the mfr fitted with the viper 4-16x50 right up till 6.30pm,got afew bunnies and I must say its a superb scope,really nice and accurate witha clear vision right up to dusk.Take my hat off to you mate it is the finest scope any air gunner could ever want with a price tag that dont blow a hole in your pocket.Nice one.

ps.The more I see through it the more I want to shoot.
